UNITED STATES PATENT OFFICE.

HENRY J. C HRS, OF WEST NEW YORK, NEW JERSEY.

TIRE.

Application filed September 9, 1915.

To all whom it may concern:

Be it known that I, HENRY J. CoHRs, a citizen of the United States of America, residing at Vest New York, Hudson county, State of New Jersey, have invented certain new and useful Improvements in Tires, of which the following is a full, clear, and exact description.

This invention relates to an improvement in tire protecting devices, the object being to provide a puncture-proof inner liner constructed to fit the inner surface of a pneumatic-tire shoe, or rather the greater part thereof, said protector being located between the inner tube and shoe. My improved protector not only will prevent punctures but will also, to a large extent, prevent blowouts.

I will now proceed to describe my invention in detail, the essential features of which will-be summarized in the appended claims, reference being had to the accompanying drawing, forming part hereof, wherein Figure 1 is a cross-sectional view of a tire provided with my improved protector; Fig. 2 is an enlarged plan view of a portion of the protector, the outer layer of rubber being removed; Fig. 3 is a longitudinal sectional view, the section being taken in a line 3-3 in Fig. 2, but having the band 2- applied; Fig. 4 is a cross-sectional view, the section being taken on a line 4-4 in Fig. 2, but having the band 2 applied; Fig. 5 is a longitudinal sectional view of one of the protector plates, the section being taken on a line 5-5 in Fig. 2; Fig. 6 is a cross-sectional view thereof, the section being taken on a line 66 in Fig. 5; Fig. 7 is a fragmentary plan view of one of the bands of my improved tire protector showing the preferred form of slots therein; Fig. 8 is a sectional view thereof, the section being taken on a line 99 in Fig. 8; and Fig. 9 is a vertical sectional view of one of the fastening devices for securing the tire protector elements together. I

My improved tire protector consists of a band 1 of rubber, leather or other flexible material, a band 2 of rubber, leather or other flexible material, and interposed plates 3 and 4 of thin material, preferably alumi- 'num. The protector, which I will designate as an entirety by 5, is placed between the inner tube 6 and shoe 7 of a pneumatic tire. the tube 6 having in contact therewith the band 1 of the protector, while the band Specification of Letters Patent.

by cross section thereof all of said grooves I 8 in said plate. The grooves 9 ofplate 3 are like grooves 8 except for their less length due to their longitudinal position. These grooves 8 and 9 are in the outer or external faces of both plates 3 and 4.

To hold the plates in position between the bands 1 and 2, I provide fasteners 10 consisting of interlocking slidably connected members 10* and 10 (Fig. 10), the member l0 being split at its lower end and flared to provide a shoulder 10. To insert the member 10 into the member 10*, the split end thereof will be compressed and inserted into the member 10 and forced downwardly until the flared end springs outwardly, after whichthe parts will be interlocked against separation until forced apart. The fasteners 10 pass through elongated slots 13 inthe lower band 1. To protect the wall of the slots I provide eyelets 14 shaped to conform to the shape of said slots (See Figs. 8 and 9). It will be apparent that while the plates 3 and 4 are secured to the band 1, they are not immovably secured thereto, as the said plates can move or slide between the bands 1 and 2, to permit the protector to accommodate itself to the inside of the shoe when the inner tube is pumped up. The upper band 2 simply acts to keep the plates out of contact with the shoe. The bands 1 and 2 are sewn together at or near their edges where the protector'tapers in cross-section, as at 15 (Fig. 4).

It will be seen (in Fig. 2) that the plates 4 are separated one from the other and also duced, the plates and 4 will also yield;

7 therefore, the tire will not be robbed of any of its resiliency. It will be apparent that the protector 5 will prevent the tube 6 from becoming punctured and will also prevent the shoe from blowing out when said shoe becomes thin or cut through. Whent-the shoe becomes thin, it cannot blow out, for the reason that the protector 5 will prevent the air within the tube 6 from forcing the tube, or rather portions thereof, through the weak spots of the shoe 7.

It will be understood that the protector 5 extends ciroumferentially around the inner tube.

Having now described my invention, What I claim and desire to secure by Letters Patent is:

1. A tire protector, arranged to fit within the shoe of a pneumatic tire, consisting of a plurality of bands and interposed protective plates arranged'in two series, separate from each other, located between two bands, and connected slidably to one of these bands,

the individual plates of each series being arranged at intervals from each other and opposite the openings between the plates of the other series, and the plates of the outer series being in contact face to face with the outer faces of the plates of the inner series.

2. A tire protector arranged to fit Within the shoe of a pneumatic tire, consisting of a plurality of bands, a series of plates carried by the'lower band and separated one from the other, a second series of plates located upon the first series and located over the spaces between the plates of the first series, means to slidably secure said plates and one of the bands together, each of said plates of the first series being longitudinally grooved, and each of the plates of the second series being transversely grooved.
